Abstract: The invention relates to a method of modifying a data set containing color component values, which method allows the component of a color in a color spectrum that is provided to be generally set to zero and thus not to use that color. For this purpose, it is provided to first select an image area of a printed product, i.e. a portion of the data set. Further, it is determined which color from the color spectrum shall not be used. The color value for the selected image area is determined. A tolerance range around the color value is fixed. In a further step, it is determined which combinations of color component values that are formed of the remaining colors of the color spectrum include color values that are within the tolerance range fixed around the color value of the selected area. Thereafter, one of the combinations of the color component values is selected.

Abstract: In order to optimize the calibration tables of a printer, and to improve the calibration for combined printing with respect to one-dimensional calibration, a method for optimized printer calibration is proposed, comprising the following method steps: a) for each primary color, the maximal value is colorimetrically limited; b) each primary color is colorimetrically linearized; c) the maximal value of the combined printing of all primary colors is determined colorimetrically; d) a definition of the resulting color range is made; e) the outer layer of the color range is determined at equal spaces; and f) the intermediate values of the resulting calibration tables are interpolated.
